Kanit is a responsive host that answers our questions quickly. His apartment is at the mid floor with a great view of the city. It's very close to MRT, although we found taking a taxi is sometimes cheaper. The area is a little dark at night but I felt safe even heading out in the evening.
The apartment is in the cozy side, but having a room is great for us with a children. There are basic utensils for you to share some takeouts (see below). Kanit equips the place with an extension cord with international plugs and 2 USB chargers which are very useful.
There are loads of restaurants of different types in W district behind and some as recommended by Kanit, but we really enjoyed exploring local treats at the Saeng Thip Alley: great local food with local prices: you can easily fill up your stomach in less than 200baht! There's also a small market nearby where we bought fruits and see what the locals are eating.
Having been to BKK for couple of times, I mostly stayed at the very busy side, but this area gives me another wonderful view of the city.
